  • a Identified exclusively with universal 16S rRNA gene amplification/sequencing, as the bacteria were seen in a Gram stain, but the cultures were negative, probably because the patient was treated with intravenous antibiotics for 2 weeks before sampling.

  • b After endoscopic removal of kidney stones, the patient developed shock, probably resulting from urosepsis (leukocyte count, 28.5 × 109 cells/liter; C-reactive protein, 297) and bleeding from the kidney. After 2 days, the kidney had to be removed. Pathological examination of the kidney revealed hematoma, microabscesses, tubular necrosis, and chronic pyelonephritis.

  • c All patients recovered from the infection.
